ESCALATING VEHKCJLE.

Application filed January 30, 1.19%. serial No. 355,081.

To all whom it may concern.

Be it known that l, WILLIAM Common, a subject of King of England, and aresident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Escalating Vehicles, of which thefollowing is a specification.

This invention has as its object to provide a vehicle which,'in one ofits several forms, is adapted for use in excavating trenches, subways,tunnels, ete., conveying the excavated material to points remote, eitheron the same level or upon an incline.

A further use for such vehicle is in the construction of buildings,masonry and cement work, including means for hauling coal, gravel, etc,ash cans and like containers, loading barges, dock handling, freight andlike purposes.

Stillanother purpose for which a modified form of the device is adaptedis that of a scenic railway apparatus, or as a toy.

These objects, in addition to others which will become apparent as thedescription progresses, are attained by the novel con- 7 struction,combination and arrangement of parts hereinafter described and shown inthe accompanying drawings, forming a ma" terial part of thisspecification, and in which v Figure 1 is aside elevational view of apreferred embodiment of the vehicle, showing the track, haulage and dumpcontrol means.

Figure 2 is a fragmentary side view of the platform locking means,looking on line 22 of Fig. 1. Figure 3 is a side elevational viewshowing the escalating vehicle at the foot of an incline, and indicatingby. broken lines the several positions assumed by it, and its pivotedplatforms, in ascending and dump mg.

Figure l is an enlarged fragmentary side view of one form of theplatform controlling device.

igure 10 is a plan view of the truck shbwing a modification in platformoperatmg means.

Figure 11 is a side view of the same.

Figure 12 is a front view showing a type of track-rail wheel.

Figure 13 is a similar view showing a type of wheel whichcan be used ona rail or level surface. 7

Referring to the drawings in detail, particularly Figs. 1 and 3, a truckis shown comprised of a rectangular frame having side elements 20, hereshown as rolled angles, their upper elements being connected at thefront by riveting the bent ends 21 of another angle 22, having a widelower element 23, while at the rear the lower elements of the angles areextended and have secured to them a plate 25, thus forming a rigidframe.

Bolted to the horizontal elements of the si e angles 20 are pairs ofbrackets, 26 and 28, respectively front and rear, in which arejournalled' pivots 27 and 29, their inner ends being secured in oppositesides of tiltmg carriers, containers, or receptacles 30 and 32, asindicated by the pans, platforms, or buckets shown, and which are suitedto the work purposes to be performed, and also in such number as may bebest suited to the work.

A pair of downwardly extending brackets 33 are bolted to the angles 20near their rear ends, the same acting as housings for the rear axle 3%to which aresecured the wheels 35. Y

The front wheels 36 are fixed on an axle 37 carried in a yoke bracket38, having between it and the element 23, a fifth wheel 39, while a kingbolt connects the parts so that the front axle is free to swivel.

Bolted to the yoke bracket 38 are angles l1. pivotally engaging thespread, lower ends d2 of a tongue 43, by which the truck may be manuallydrawn and steered.

The lower spaced elements 42 of the tongue extend parallel and areadapted to be received in slots 4 1 formed in the'truck elernents 23, towhich are pivotally attached haJ'sp-like clips by which the tongue, whenin a raised position can be locked,

thereby maintaining the front axle parallel with the rear axle, causingthe truck to move on a straight course.

The wheels 36, as shown in Fig. 9, are plain cylinders adapted to movefreely on any level surface, or be guided by the vertical elements ofangle rails 46. Other types of wheels 36', are adapted to be used withordinary track rails, as shown in Fig. 12, while Fig. 13 shows a Wheel36", adapted to be used either on a plain level surface or on a rail asindicated.

Secured to the horizontal plate 25 is a vertical bracket 48 supportingan angular bracket 49. A spindle, journalled in the upper portion of thebracket 48, has secured to it an operating hand wheel 50, while on theouter end of the spindle is fixed a bevel gear 51 meshing with a matinggear 52 fixed on the upper end of a vertical shaft 53, rotatable in thebracket 49 and plate 25, its lower extending end having secured to it adrum 54, to which is attached one end of a haulage cable 55, the otherend of the cable being fastened to a fixed object, as the post 56, asshown in Figure 3.

Obviously the cable may be attached to the truck and the winding donefrom a fixed point in a manner reverse to that indicated by whateversource of power that is convenient.

A look for holding the carriers 30 to the truck frame is shown in Figs.1 and 2, the. same consisting of a bracket fastened to the truck frameside and pivotally containing a rod havingza handle 61 projecting at anangle from one end', while from the other is an arm 62 having a bent end63 engageable over an angle bracket 64, fixed on the side ofthe carrier30, and preventing it from tipping until the handle 61 is pulledoutwardly, or other equivalent means used.

These trucks are adapted to be drawn up inclined surfaces, as indicatedbest in Fig. 3, in which a stairway is shown having tracks 46 adjacentto the ends of the steps,

the tracks ending in stops 46' which limit the, forward movement of thetruck.

In order to maintain the several carriers, all of which are pivotallysupported by the truck frame, in a horizontal plane, irrespective of theinclination of the body of the truck, control devices are used of whichthe preferred embodiment consists of a pair of levers 67 and 69 rigidlysecured atone side of the truck frame to the points 27 and. 29, theselevers being at all times at right angles with the planes of thecarriers 30, and are pivotally bolted at their upper ends to aconnecting bar 68 so that all of the carriers are oscillated as a unit.

The front lever 67 has an a lar arm by a locking device 70, a bar 71pivotally engaging at its outer end a plate or head 72.

In opposite ends of this head are secured headed spindles 73 on'whichare rotatably mounted wheels 74, having concave faces adapted to engagewith a tubular rail 75 as shown in Figs. 1, 4 and 5, or wheels 74'having grooves engageable with rectangular rails as shown in Figs. 6 and7.

These rails, of whatever cross section may be preferred, are bent toform fixed elongated cams and rigidly secured at spaced intervals alongtheir length to adjacent walls so as to extend lengthwise above therails 46, and may be used as hand rails along the stairs, but so shapedthat their cam-like profile will, by reason of the wheels, levers andconnections, cause the carriers toremain truly horizontal during thetravel of the truck.

In order to cause the receptacles to tilt and deposit their contents, ashort rack section 150 is fixed on an appropriate support along thetrack where dumping is to take place, and engageable with this rack is agear segment 151 whose hub is keyed or otherwise secured to a carrierpivot, as 29, in such manner as to cause the pivot and carrier to partlyrotate as the segment 151 engages the rack 150, thereby dumping saidcarrier.

Thus the dry ingredients of mortar, cement and the like may be conveyedin separate receptacles,-- dumped and commingled with .water supplied bythe pipe 75 having spray heads 76, from the tank 77, the valve 77 beingopened automatically by the truck, at the end of its run, striking thevalve handle 77', so as to moisten and mix the ingredients, the mixedcontents passing down the inclined grooved planes 78, which areadjustable by the bolts 79, as best seen in Fig. 3.

It will be clear that the dumping of the carriers may take place at-theother terminus of the truck run, or by providing racks 150 for co-actionwith segment 151, also that any number of the carriers may be used withone truck compatible with its capacity.

A modified means of dumping the carriers is shown in Figs. 10 and 11, inwhich a pair of bevel gears 80 and 81 are secured directlyin the bracket85 and having beyond the.

worm a spur gear 89 engageable with a rack 90 station'a adjacent thetrack, a similar but reverseii rack 91 being in opposed relation and ata little distance therefrom.

Thus when the gear-engages the rack 90,

66 containing a socket in which is secured, obviously the carriers aretipped to such an extent as to cause dumping, but as the truck continuesto advance and the gear engages the track 91, the carriers are rotatedinto a horizontal position, it being'understood that the length of theracks are such as to accomplish the purpose of transmitting the degreeof rotary motion required in the shaft 8%.

lln order to hold the gear 89 from jarring loose, and thus inadvertentlytilting the platforms 30, a latch 93 ispivoted to the frame, the sameresting on a bracket 94, rigidly extending from the frame, the latchbeing held in operative position relative to the teeth of the gear by aspring 95, and pivoted with an extending curved arm 96 reaching outwardbeyond the side of the ear.

g A fixed rejection 97, of suitable length is arrange adjacent to theside of the track and, as the truck moves past the, dumping point,strikes the arm, releasing the catch or latch, from the teeth of thegear and allowin it to be rotated.

aving thus described my invention what I claim as new and desire tosecure by Letters Patent, is

1. An escalating vehicle comprising a truck, a track therefor, saidtrack having an inclined portion, a. carrier pivoted transversely insaid truck, a cam rail along said track, and pivotal connections betweensaid cam rail and said carrier to hold the carrier in a horizontal planewhether the truck is in a horizontal plane or an inclined plane upon thetrack;

2. An escalating vehicle comprising a truck, a track therefor, saidtrack having an inclined portion, a carrier pivoted transversely to saidtruck, a cam rail along said track, and pivotal connections upon saidtruck with means adapted to travel along said rail, to hold the carrierin a horizontal plane whether the truck is in a horizontal plane or aninclined plane upon the track.

3. An escalating vehicle comprising a truck, a track therefor, saidtrack having an inclined portion with a fixed rack at its highest point,a cam rail along said track, pivotal connections upon said truck withmeans adapted to travel alon said rail, to hold the carrier in ahorizontal plane whether the truck is in a horizontal plane or aninclined plane upon the track, and spur means extended from said pivotalmeans to engage said rack, thereb causing the carrier to be rotated fordu'mpmg purposes.

4:. A escalating vehicle comprising a truck, a track therefor, saidtrack having an inclined portion, a number of carriers pivotedtransversely in said truck, a cam rail over said track, levers extendingvertically from said carriers, connections between said levers, an armextending angularly from one of said levers, and a pair of opposed guidewheels carried at the end of said arm for engagement with said rail.

5-. The combination, with a truck, of a carrier pivotally mountedthereon, a track including an inclined portion, a cam rail, meansco-acting between said carrier and rail to maintain said carrier in ahorizontal plane when the truck is inclined, and. means for tilting saidcarrier to dump its contents at apredetermined point in its path oftravel.

In testlmony whereof I have signed my name to this specification.

WILLIAM CORMACK.
